I'm going to mark this as an enhancement. When the inheritance graph is
non-trivial, I don't think it's so obvious which, if any, of the ancestors
should be picked. Perhaps the user should decide.

So I'm skeptical this is a good idea.

Meanwhile, it does work for classes, which make sense because classes are
single inheritance. A common root, if there is one, would be only one.
